Reporter from the 26 held in Hangzhou was informed of the news conference, the team of experts from the Zhejiang University, Tsinghua University, University of Hong Kong and the National Center for disease control, complete the research and thesis of this important topic to write. Through the sampling and analysis of occurred in 4 patients in Zhejiang and they may be related to the live bird markets of chicken, duck, quail and dove H7N9, the experts found that, H7N9 virus isolation and the live bird markets isolated from patients in the chicken strains of the virus gene sequences are highly homologous.

　　“这是我们首次通过实验证明、而非猜测，获得H7N9病毒从禽类向人类传播的证据。该团队的领导者、国家卫生和计生委人感染H7N9禽流感疫情防控工作专家组专家李兰娟院士说。

　　"This is the first time we proved by experiments, rather than speculation, obtain evidence H7N9 virus from birds to humans spread." The group leader, national health and Family Planning Commission of human infection with the H7N9 avian influenza epidemic prevention and control work expert group expert academician Li Lanjuan said.

　　不仅如此，研究团队在对病毒基因组研究后发现，病毒的H7基因中发生氨基酸位点发生变异，这使得病毒更容易从禽类感染到人。“如果PB2基因的627和701氨基酸位点同时发生变异，将会导致有效的人传人。论文这样表述。目前研究团队已发现了701位点的变异。
